mcmillan are they really this busy...

i am going to start a new build and am wondering if there is anyway to get components faster. i want to order a mcmillan htg stock with an adjustable cheek piece. are there any suppliers that have these on hand so i can get one faster than waiting the 6 months. does anyone else have this style stock that is of the same quality. i would even buy a used one do you guys know of any places to buy them used?
